Dusky sharks, also known as bronze or black whalers, are long-distance swimmers, according to National Geographic. While not one of the world's four most dangerous sharks, it has an incredibly powerful bite.

As seen in the video above, captured by a local news crew, the shark at Bulcock Beach appeared to be attempting to come ashore. Two men in the video approached the shark as it swims mere feet from the breakers.

Astonished bathers watched while Welsh tourist Paul Marshallsea and another man grabbed hold of the shark’s tail and attempted to nudge it out to sea, reports Wales Online. Marshallsea, a 62-year-old grandfather, suddenly found himself on the defensive as the shark lunged at him. Its babies had been swimming nearby, and it felt threatened by the sudden presence of the men.

"Babies were swimming through my legs," Marshallsea told Wales Online. "A shark that one minute ago was so docile now just nearly took my leg off in a split second – it was that quick.”

Still, Marshallsea said helping the dangerous but beautiful creature was the right decision.

“People might say it was a stupid thing to do but when you see a beautiful beast struggling to survive up close and personal you somehow tend to respect it and want to help it," he said, per Wales Online.

In this handout picture released by Awashima Marine Park, a 1.6 meter long Frill shark swims in a tank after being found by a fisherman at a bay in Numazu, on January 21, 2007 in Numazu, Japan. The frill shark, also known as a Frilled shark usually lives in waters of a depth of 600 meters and so it is very rare that this shark is found alive at sea-level. Its body shape and the number of gill are similar to fossils of sharks which lived 350,000,000 years ago. (Photo by Awashima Marine Park/Getty Images)
